I was thinking about this when I heard that Phyllis Diller died at 95. Here we would say that she had a good innings. Do Americans say that? It's a cricketing term because 95 or 88 or 100 or a large number like that is a good amount of runs to make, ie a good score.

it's a known phrase in the UK, though I think it's becoming less common

It means to make a U-turn. An example would be "Oh, I missed my exit. I'll flip a witch and go back."

Here in New England they say, "Bang a u-ie" (pronounced yooie).

A couple other regional sayings that drive me nuts are "Not for nuthin, but..." and "So don't I" (for "So do I").

We say "bang a u-ie" in NYC too. And when you are parallel parking you start in at an angle then you "cut the wheel" (or "cut it") to turn in the other direction to straighten out.

One of my favorite regionisms is deli sandwiches on a long roll. In NYC they are "heros" you can get a regular hero (about 8-12 inches long) or a 3 or 6 foot for parties. A NYer would probably know what you meant if you said a "sub" or "hoagie" but we'd know you were from out of town.

A lot of NY-isms are just us speaking quickly. lots of people know "fuggetaboutit" but we also often say/hear "lemmegeta" (let me get a) and "cannageta" (can I get a) or "omigosh" (oh my gosh) "s'up" (what's up).

And of course there is "yo" which can mean hello, hey you, excuse me, what, you dropped something, come here, go away, you startled me, that's outrageous, and several other things all depending on context and tone. One can have an entire conversation of "yo!" "yo?" "yo" "yo" and the two people will totally understand (they have just said "hey you!" "what?" "you dropped something" "thanks"). Of course its also a thing to call a person - "s'up, yo?" "good lookin' out yo" "yo thanks".

Despite now living in CO, I grew up in Pennsylvania and learned "flip a witch".

Speaking of northwest PA...we have a few regional "things" (not necessarily sayings) and a lot of a regional accent. Y'ins is our form of y'all. Gum band and rubber band. "Go red up your room" means to go clean up your room, or you would red up because people are coming over.

Dark Boyfriend, Texan, likes to say, "How much time do you like?" to ask how much longer it is going to take me to do something. Drives me nuts.

Someday I'm going to write down all the slang terms for getting drunk, dying and playing Scrabble, just to see which list is the longest. I suspect Scrabble, because it's the most fun!

In Massachusetts, what's known elsewhere as a roundabout or traffic circle is a rotary.

These are very old Bostonisms I learned from my mom: A straight pin is a common pin (to distinguish it from a safety pin). Baseboards are mopboards. If you have a double sink, the side that isn't being used to wash the dishes in is the settub.

I haven't lived in New England for 30 years, so I don't know if anyone still says "tonic" for soda or pop. When I was a kid "soda" meant only one thing: an ice cream soda. Coke, Pepsi etc. were tonic.

This is a pronunciation thing, not a saying thing, but how do you pronounce "sauna"? Like "fawn" and "dawn" or like "sauerkraut"?

What we called the "feeder" in Houston is called an "access road" or "frontage road" elsewhere -- the road that goes along the side of a highway for on-and-off access.

That is so confusing. We were in Houston for a wedding and the driving instructions to get to the rehearsal dinner said "Take Feeder Road." DH and I keep looking for a road named "Feeder." We flipped a witch about four times before I said "Maybe 'Feeder' means 'frontage.'"
